perfect as it gets , better than all primes .reviewed December 8th, 2007 (purchased for $980)
this and the 70-200f4LIS kill all primes.
10 out of 10 points and recommendedresolution , lack of CA , lack of distortion , super fast AF,none
my copy is EXTREMELY sharp , in fact , sharper than all my primes in this range.reviewed December 8th, 2007 (purchased for $1,100)
the DO Af is super fast , there is no CA .
the color rendition is beautiful with this lens.
highly recommended , considering its over all IQ and build quality and AF speed , this is the best tele zoom for handheld photography.
I also have the EF70-200f4LIS and both are superb.
But I perfer my DO for 2 reasons: 1 it is shorter .2 it is BLACK.
4 out of 10 points and not recommendednonehorrible lens ,slow AF, lots of CA, lack of contrast.
just simply worst Canon tele lens , PERIOD.reviewed December 8th, 2007 (purchased for $450)
AF slowly and hunts like annoying bee behind your ear.
It feels cheap , the front element rotates and the IS is not as effective as the one on my DO or f4LIS.
I bought it in Bangkok and thought use it as back up to my DO and 70-200F4 LIs , but sold it as it was truly horrible lens.
10 out of 10 points and recommendedsuperb resolution, super accurate AF , fast HSM focus, well built.a bit pronounced CA in high contrast area
a great lens, my copy is extremely sharp , maybe as sharp as my EF-S10-22 , and a bit less sharp than my EF-S17-55f2.8IS.reviewed December 8th, 2007 (purchased for $450)
I think this lens is much sharper than my Tokina 12-24 and 17-40L, both of which are replaced by this lens.
this is the only one lens from third party that I love and keeping in my kit.
2 out of 10 points and not recommendedbuild quality (that is good)horrible color , horribe resolution , pronounced CA, pronounced distortion
bought this to try to replace my travel lens the EF-S17-85IS , but this is a horrible lens.reviewed December 8th, 2007 (purchased for $450)
I kept my Canon Ef-S17-85IS as my travel and day light lens.
I have EF-S17-55f2.8IS for my work and serious shooting so this lens has no place in my kit.
10 out of 10 points and recommendedfreakishly fast AF, extremely sharp , excelelnt flare resistance, inconspicuous lookCA.
get it if you need this forcal length.reviewed December 8th, 2007 (purchased for $300)
there is no better lens than this , I sold my 70-200f4LIS to get this one since I needed a inconspicuous , samll lens for street and PJ work.
10 out of 10 points and recommendedfast AF (although not as fast as my 85f1.8), sharper than all primes in this range.expensive and white .
Although this lens is almost perfect optically , I sold it for a couple of small lenses (85f1.8 and 100f2) because it was just simply too conspicuous and bold.reviewed December 8th, 2007 (purchased for $1,200)
I was arrested in Burma and other places for this .
I love the quality of this lens but I can not have it because it got me arrested or my face punched a few times times .
When you are working as some kind of travel photog for a mag or like that , you some times need to be in dangerous places like Burma or Iran , and you are not safe with a white lens there.
People kill you seriously.
That said , if I were shooting landscapes or day light sports , or even some portrait as a hobbist , I love this insanely sharp lens, though, I think people especially L snobs are too obsessed with resolution chart sharpness and forget about anything else.
If I were a hobbist and printing out no bigger than A3 , I will buy an EF-S55-250IS(just very sharp and light , though not as contrasty as this L lens).
But for pro sport in day light or landscapes in night(IS gives me about 5 stop advantage, so when I usually need ISO1600 , I can use ISO200) , it is a super lens because of the Af and weather-sealing.
Just not use it in Burma.
10 out of 10 points and recommendedlight , inconspicuous , fast Af , lack of CA, good resolution not excelelnt , thoughmicro USM rather than the RING, cheap buid.
just got it to replace my 70-300IS , it is ok , though AF to slow for my needs , so replaced with the DO IS.reviewed December 8th, 2007 (purchased for $230)
it is at least as sharp as the EF70-300IS non DO, the DO is a bit sharper with better color.
if you are a hibbist or back packer and wanna go light and inconspicous , then get it .
you wont regret it, but I do not use it for my work.
I use 200L for my work .
UP date: I got it in Japan as well ,when I worked there 5 days a go , and I bought it at a Fuji camera , which is known to be the cheapest camera store in the world.
10 out of 10 points and recommendedsuper fast AF when not used as a macro, the super sharp optics , excellent buildnone at all.
this is the lens I love more than any other lenses I 've used , this lens is sharper than all Ls . PERIOD.reviewed December 12th, 2007 (purchased for $340)
there is no better lens than this , this lens is not comparable to the low level Tamorn Sigma macros priced around this one........... this one does NOT extend when it focuses and this lens is so compact , with super fast AF .
I use this for many applications but I think this one really shines when shooting street candid stuffs .
I was shooting cats chasing a rat , fighting , this lens AFed stop on all the time .
last monday , I went to Cambodia for Thai visa , shooting many people in really shockingly poor country especialy at border , this lens took amazingly honest simle of people there , if I had my 70-200f2.8 or 4 LIS , people never smiled and even before that I am not sure if I got through there safe.
This is a super lens , no doubt about that.
This is the best example of how much better an EFS could be than an EF counterpart.
Compare this to the lousy 100 f2.8 , you will know what I mean.
Also , compare the superb EF-S10-22 against the old and over priced EF17-40L, you will know FF is not the future, in 10 years , there will be no FF hopefully.
I hope EOS 1 and Nikon D3 will be gone with these L and 5D snobs with FF -film nostalgia ......
We need an EF-S100 f1.4IS to work with this stunning lens.
